librsync  2.0.1
Whole-file API

Some applications do not require the fine-grained control over IO, but rather just want to process a whole file with a single call. librsync provides whole-file APIs to do exactly that.

These functions open files, process the entire contents, and return an overall result. The whole-file operations are the core of the rdiff program.

Processing of a whole file begins with creation of a rs_job_t object for the appropriate operation, just as if the application was going to do buffering itself. After creation, the job may be passed to rs_whole_run(), which will feed it to and from two FILEs as necessary until end of file is reached or the operation completes.
